The New York Order of Incorporation of Post-Adoption Contact Agreement (Agency) is an agreement established by New York State law. It allows for adoptive families to set up a post-adoption contact agreement, which outlines the terms of communication between adoptive families and the adopted person's birth family. This agreement is voluntary and can be established with the help of an agency. The types of New York Order of Incorporation of Post-Adoption Contact Agreement (Agency) include open adoption, semi-open adoption, and closed adoption. Open adoption is when contact details are exchanged and there is a pre-established communication plan. Semi-open adoption is when identifying information is not exchanged, but contact is still established with the help of a third-party intermediary. Closed adoption is when no contact is established between the birth family and adoptive family.
